Answer:
its a conductor because it conducts electricity
Explanation:
From the calculations, the acceleration of the elevator is obtained as 1.5m/s^2
<h3>What is acceleration?</h3>
The term acceleration has to do with the rate of change of velocity with time.
Given that;
u = 9.2 m/s
v = 15.8 m/s
t = 3.8
a = ?
The v = u + at
a = v - u/t
a = 15 - 9.2/3.8
a = 1.5m/s^2

Answer:
the minimum thickness (in nm) t = 102.5 nm
Explanation:
t = thickness of the film
n = index of refraction = 1.61
m = order = 1
∝ = wavelength = 330 x 10-9 m
so we have the formula
2nt = m∝
2 (1.61) t = (1) (330 x 10-9)
then...
t = 1.025 x 10-7 m
converting...
t = 102.5 nm
The temperature rises of in the block if the current flows for 10 minutes is, 34.78K.
To find the answer, we need to know about the power of the electric heater.
<h3>How to find the temperature rise of in the block if the current flows for 10 minutes?</h3>
- We have given with the variables,

- We have an expression the heat given to the system as,
ΔT
- We have to find the temperature rise ΔT,
ΔT 
Thus, we can conclude that, the temperature rises in the block if the current flows for 10 minute is 34.78K.
